MALT-DRIER.

SPECIFICATION forming part; of Letters Patent No. 325,018, dated August25, 1835.

A pnlicaticn filed March 2'7, 1835.

T0 at whom it may concern..-

Be it known that I, ADAM SCHULTZ, of Cincinnati, in the county ofHamilton and State of Ohio, have invented certain new and usefulImprovements in Apparatus for Drying Malt, of which the following is aspecification.

This invention relates to apparatus for drying maltand other material;and it consists in the novel combination of devices hereinafterdescribed, and specifically set forth in the claim, reference being madeto the accompanying drawings, illustrating my invention, in which Figure1 is a side elevation of my improved malt-drier. Fig. 2 is an endelevation, and Fig. 3 a plan view, thereof. Fig. 4 is a detached plan ofthe malt-feeder.

Similar letters of reference indicate similar parts.

The machine consists of a frame-work, A, of wood or iron, upon which aremounted the traveling floors or aprons C. These aprons are endless bandsof wire-cloth of any desired mesh, stretched around the hollow drums B.The drums are mounted upon shafts or gudg' eons b I), provided withjournals which turn in bearings secured to the frame-work A. The boxesor bearings of the shafts b, at the left side of the machine, Fig. 1,are rigidly secured to the frame-work, while the boxes of the shafts I),at the right side of the machine, are adjustable in a horizontaldirection by means of the tempering-screws 7), whereby any desiredtension may be given the wire-cloth aprons (J.

Mounted upon the side rails, A, of the framework A are cross-ties (t a,upon which rest and are secured the iron rails c 0. These are set closeunder and parallel with the motion of the aprons O, and prevent anoverstrain of the latter by the load of malt.

Between the upper and lower portions of the aprons G steanrheating pipesG are placed, through which steam circulates and furnishes the heatrequired to vaporize the moisture in the malt. These pipes are arrangedto receive live steam in the lower tier within the lower apron O andpass the same from the lower tier to the tier next above, and so on tothe uppermost tier of heating'pipcs in the ma 0 chine.

Sprocket'whecls D, of uniform diameters,

(X0 model.)

are keyed to the shafts of the drums B, around which are trained thelink-belts 1*], whereby the drums at the opposite ends of the machineare caused to revolve by positive connectors and at the same speed. Toone end of the shaft 1) of the upper drum, B, a worm-wheel, H, is keyed,into which the drivingworm H meshes. The worm is keyed to thedrivingshaft 71, which turns in hearings in the housing H, secured tothe flll']l6-\\'Ol1( A. H may be a spur-wheel or belt-pulley to receivethe power required to operate the machine.

Spur-wheels F, keyed to the shafts b of the drums B, give motion to allthe drums below the uppermost one. These are of uniform diameter, andcause the drums B and aprons C to move at uniform speed, and, as shownby the arrows in Fig. 1, to move in opposite or alternate directions.Thus the apron at the top of the machine travels from left to right,while the apron next below travels in the opposite direction, or fromright to left, the alternate aprons traveling in the same directions. Inthis manner the maltis carried from the hopper J to the right side ofthe machine, there dumped upon the end fender, K, which directs it uponthe apron 0 next below, which apron carries it back to the left side ofthe machine, where it is dumped on the end fender, K. This in turndirects the malt upon the apron (1 third in order from the top ofmachine, which again carries it from left to right, and so on accordingto the number of aprons, of which there may be any desired number in themachine.

The hopper J is provided with a toothed feed roll or agitator, J,turning in journalbearings in the ends of the hopper, and driven fromthe upper drumshaft by the sprocket wheelsj j and link-belt J A fixedcomb or rack, J is set in one side of the hopper, by means of which andthe feed-roll the malt is regularly supplied in granular form from thehopper to the upper apron G.

The aprons G are in width equal, or about equal, to the length of thedrums B, and are attached to the linlebelts E by the clips or lugs e,which project inward from the belts, as shown in Fig. 3, and are rivetedto the edges of the wire-cloth apron. In this man nor the aprons areuniform] y strained through out their length or circuit, and the drums Bare simply carriers around which the aprons are guided; but the drivingstrain required to move the aprons O is obtained directly from thelink-belt E through the clips 6, as described.

L is a hood or inverted hopper, placed over the machine, which collectsthe vapor arising from the damp malt, and M an eXhaustfan, which drawsthe vapor from the hood L down through the pipe L and expels it from theroom in which the machine is worked.

70 7c are side fenders, secured to the frame A upon each side of themachine, to direct the malt inward from the edges of the wirecloth apronC while falling from one apron to the next below.

The operation of the machine is continuous. Motion being given the drumsB and wirecloth aprons 0 through the driving-gear or pulley H, worm andworm-gear H H, and spurgears F, and sprocket-wheels D, and link-belts E,the malt is regularly supplied from the hopper J to the upper of apronsC, while upon this apron the damp malt travels over the n pper tier ofsteam-heating pipes G, and a portion of the moisture vaporizedtherefrom, and is regularly delivered from the right end of this apron Oto the apron next below, when it is further heated over the tier ofsteam-heating pipes in this apron and then delivered to the apron nextbelow, where it travels over the tier of steam-heating-pipes in thisapron and is finally delivered to the lowermost apron G in the machine,upon which it is completely dried.

Any desired number of wire-cloth aprons C may be used, but I have shownfour only to illustrate the general arrangement of 'my improvedapparatus.

The foraminous nature of the endless traveling aprons is very importantin that the heat from the pipes is permitted to pass upward through themeshes of the wire-cloth into direct contact with the malt carriedthereby, thus largely increasing the efficiency of the machine.

The width and length of the aprons C will depend upon the amount of maltto be dried in a given time, and the speed at which the aprons willtravel will be adapted to the number and.length and width of the apronsto cause the malt to be completely dried before it leaves the lowermostapron.

Having thus described my invention, what I claim is In a malt-dryingmachine, the combination of a series of drums, B, the seriesot'foraminons aprons alternately traveling in opposite directions, thespur-wheels F, connecting the shafts of the drums at one end of themachine, the hopper J, the agitator J, and the link-chain J connectingthe shaft of the agitator with the upper drumshaft, substantially asdescribed.

In testimony whereof I have signed my name to the foregoingspecification in the presence of two subscribing witnesses.

ADAM SCHULTZ.
